22 islShow islShow SYNOPSIS Displays interswitch link (ISL) information. islshow DESCRIPTION Use this command to display the current connections and status of the interswitch link (ISL) for each port on a switch. The command output includes the following information: • Node world wide name (WWN) • Domain ID • Switch name • ISL connection speed, if applicable • Bandwidth • Trunking enabled, if applicable • QoS enabled, if applicable • Encryption enabled, if applicable • Compression enabled, if applicable When issued on a switch that is part of a logical fabric configuration, the islShow command displays logical interswitch links (LISLs) along with regular ISLs. However, speed (sp) displays N/A for logical ports. The bandwidth (bw) displayed is the sum of the bandwidth of all extended ISLs (XISLs) that form the LISL. A shared ISL (XISL) connects the base switches and is shared by different logical fabrics. It allows devices to communicate with each other within the logical fabric. Connection speed is not applicable to LE_Ports or VE_Ports. For these port types, speed displays as "sp:-------". NOTES The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. OPERANDS None EXAMPLES To execute islshow in a base fabric: switch:user> islshow 1: 2->300 10:00:00:05:1e:43:00:00 100 DCX \ sp: 8.000G bw: 32.000G TRUNK QOS 2: 8-> 3 10:00:00:05:1e:41:8a:d5 30 B5300\ sp: 4.000G bw: 16.000G TRUNK QOS 3: 19-> 10 10:00:00:05:1e:41:43:ac 50 B300 sp:\ 8.000G bw: 64.000G TRUNK To execute islshow in a logical fabric: switch:user> islshow 1: 33-> 29 10:00:00:60:69:80:4f:84 sp: 2.000G bw: 4.000G TRUNK 2: 39-> 7 10:00:00:60:69:45:68:04 sp: 2.000G bw: 8.000G TRUNK 3: 41-> (incompatible) 4: 47-> (incompatible) 5: 95-> 0 10:00:00:05:1e:01:0b:4a sp: 2.000G bw: 2.000G TRUNK 3 B3200 \ 4 B3850 \ 15 B5100 \ 470 Fabric OS Command Reference 53-1001764-01
